Study on feasibility of functional regression testing

In order to implement functional regression testing more efficiently,after a detailed analysis of the key factors which impact the reusability of test case,an evaluation method of testing methods based on the feasibility of regression testing are proposed.The paper represents two methods to improve the efficiency of regression testing greatly.One of which adopted the means of multi-level driven to generate the automated testing scripts.The other one designed and implemented a cooperating testing platform,which can not only de-creases the cost for testing,but also improves the degree of automation in testing.It is proved that thus methods have a very important guidance meaning and practical value for the improvement of feasibility of functional regression testing.
